natural selectionnatural selection
- Recently graduated from college, Darwin joined up with a British Navy mapping ship that was going on an expedition around the world.
- Darwin wasn’t the first scientist to study the idea of evolution; however, he was the first to come up with a workable theory about how, exactly, this evolution took place.
- Darwin's research focused on:
- The adaptation of a species in order to survive in various conditions
- The variation among individuals that caused them to live while others died
- The passing on of those advantageous traits
Natural selection is part of Darwin's theory of evolution saying that those individuals within a species that don't adapt well to their environment will eventually die off, while those that do adapt will continue on with future generations.
Facts About Darwin's Research
An example of natural selection are insects which are resistant to pesticides.
- (evolutionary biology) A process by which heritable traits conferring survival and reproductive advantage to individuals, or related individuals, tend to be passed on to succeeding generations and become more frequent in a population, whereas other less favourable traits tend to become eliminated.
- (quantitative genetics) A process in which individual organisms or phenotypes that possess favourable traits are more likely to survive and reproduce: the differential survival and reproduction of phenotypes.
